What is true regarding the BGP protocol?

• A. It is a distance-vector routing protocol
• B. It does not use path attributes
• C. It cannot handle multiple paths
• D. It is a link-state routing protocol

Answer: (A)

The Border Gateway Protocol (BGP) is indeed classified as a distance-vector routing protocol. It is primarily used to exchange routing information between different autonomous systems on the internet. BGP makes routing decisions based on path vector mechanisms, wherein it uses information about the entire path that a route takes, rather than just the distance to the destination. In the context of distance-vector protocols, BGP can be thought of as using a modified distance-vector approach since it shares routing information about the distance (the number of hops) along with the full path to the destination. This characteristic allows BGP to choose the best path based on various attributes, such as the path length, policy rules, and other factors. The incorrect choices highlight other routing protocol features that do not apply to BGP. BGP does indeed utilize path attributes, which are critical in determining the best path when there are multiple options. Furthermore, BGP is capable of handling multiple paths, allowing for redundancy and load balancing. Unlike link-state protocols, BGP operates using a different methodology that emphasizes the relationships between autonomous systems rather than maintaining a complete view of the network topology, which is characteristic of link-state protocols.
